Cloud9 v3 SDK core, a Node.js-based web IDE platform that can be self-hosted and extended with custom plugins. It lets developers build a customized browser-based IDE on top of the Cloud9 codebase.

Use cases

  • self-host a browser-based IDE on my own server
  • build custom plugins to extend a web IDE
  • create a tailored cloud development environment
  • run an online code editor for a team workspace

When to choose

  • you want to build a custom web-based IDE on the Cloud9 codebase
  • you need a self-hosted browser IDE with plugin extensibility
  • you're maintaining legacy Cloud9 v3 deployments

When to avoid

  • you need a maintained, actively developed IDE
  • you want a modern editor with current Node.js support
  • you just need a code editor without plugin development
